First thing is to take a deep breath and let it out, and then think of the consequences. If that doesn't work, keep trying, don't give up, or in this case give in.

I too went from short term relationship to the next, so have a others. I found strength in going to 12 step meetings.

Most importantly, finding a higher power to let the higher power take what you have delt with. Celibacy may be a good idea for 1 week. Going to counseling is helpful.

Most of all be true to who you are. If you don't want to cheat distraction helps, meditation helps, and any DBT skill helps, including splashing your face with cold water.

I have found 54 days of success doing all of the above. Along with reading about the sex/relationship addiction. Start with "Out of the Shadow" Patrick Carnes (I think that is the author) does an excellent job explaining what you can do and about the addiction. I have found that understanding helps. If you need to reach out, do!!
